    On mars there is an atmosphere which contains carbon dioxide (95.32%), molecular nitrogen (2.6%) and argon (1.9%). i think you got confused with earth moon, our moon doesn't have atmosphere.Perseverance will search for past microbial life and collect soil samples and stuffs. Get ready to see the spectacular launch on 30th july UTC.

    ok so u mean drone flyes on co2 gases right

    eduncle-logo-app

    it use co2 to produce drift & it's not possible for moon right???

    Drones are powered by propellers which push air in downward direction to maintain height. drones need air density, nature of air doesn't matter. Nasa used parachute in landing of curiosity rover, but they use burner to land on moon, that's why landing on mars is easier than moon.

    because moon doesn't have atmosphere , parachute is of no use, remember chandryaan 2 animation.
